Title: Second-second moments and two observers testing quantum nonlocality
Authors: Adam Bednorz
Abstract summary: We prove that one requires three observables for each observer for a maximally entangled state and two observables for a non-maximally entangled state. Finding an example for quadratures or position and momentum is left as an open problem.

Abstract: We show that rejection of local realism in quantum mechanics can be tested by Bell-type inequalities for two observers and low-order moments of continuous and unbounded observables. We prove that one requires three observables for each observer for a maximally entangled state and two observables for a non-maximally entangled state and write down appropriate inequalities and show violation by quantum examples. Finding an example for quadratures or position and momentum is left as an open problem.

Self-testing of an unbounded number of mutually commuting local observables [0.0]
It is well-studied that locally commuting or compatible observables cannot be used to reveal quantum nonlocality. We show that the optimal quantum violations of suitably formulated bilocality and n-locality inequalities in networks uniquely fix the observables of one party to be mutually commuting.

Observation of partial and infinite-temperature thermalization induced by repeated measurements on a quantum hardware [62.997667081978825]
We observe partial and infinite-temperature thermalization on a quantum superconducting processor. We show that the convergence does not tend to a completely mixed (infinite-temperature) state, but to a block-diagonal state in the observable basis.

Recycled entanglement detection by arbitrarily many sequential and independent pairs of observers [0.0]
We investigate the witnessing of two-qubit entangled states by sequential and independent pairs of observers. We find that a two-qubit entangled state can be used to witness entanglement arbitrarily many times.

Events in quantum mechanics are maximally non-absolute [0.9176056742068814]
We prove that quantum correlations can be maximally non-absolute according to both quantifiers. We show that chained Bell inequalities (and relaxations thereof) are also valid constraints for Wigner's experiment.

Quantum indistinguishability through exchangeable desirable gambles [69.62715388742298]
Two particles are identical if all their intrinsic properties, such as spin and charge, are the same. Quantum mechanics is seen as a normative and algorithmic theory guiding an agent to assess her subjective beliefs represented as (coherent) sets of gambles. We show how sets of exchangeable observables (gambles) may be updated after a measurement and discuss the issue of defining entanglement for indistinguishable particle systems.

Observers of quantum systems cannot agree to disagree [55.41644538483948]
We ask whether agreement between observers can serve as a physical principle that must hold for any theory of the world. We construct examples of (postquantum) no-signaling boxes where observers can agree to disagree.

Non-locality and quantum measurement are two fundamental topics in quantum theory. Non-locality sharing among multiple observers is predicted and experimentally observed. Double EPR steering can be demonstrated simultaneously while double Bell-CHSH inequalityviolations are shown to be impossible.

Entropic Uncertainty Relations and the Quantum-to-Classical transition [77.34726150561087]
We aim to shed some light on the quantum-to-classical transition as seen through the analysis of uncertainty relations. We employ entropic uncertainty relations to show that it is only by the inclusion of imprecision in our model of macroscopic measurements that we can prepare a system with two simultaneously well-defined quantities.

A strong no-go theorem on the Wigner's friend paradox [0.0]
We prove that if quantum evolution is controllable on the scale of an observer, then one of 'No-Superdeterminism', 'Locality' or 'Absoluteness of Observed Events' must be false. We show that although the violation of Bell-type inequalities in such scenarios is not in general sufficient to demonstrate the contradiction between those three assumptions, new inequalities can be derived in a theory-independent manner.
